TEMPQRARYBDER on LOOSE- SHEET HOLDER.'

To all whom t may] concern.' l

Bc itknown that I, GEorgGn P. iVrGorNroN,

a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new andnseful Improvements in Temporary Binders' or Loose-Sheet Holders, of which the following is aspeciiication..

This invention relatesto improvements in temporarybinders or loosesheet holders.

This invention relates particularly'to temL -porary binders orloose 'sheet holders of the ,type shown inl Letters Patent, #851,276,

issued toHarry E, -Bushongo April 23,1907, and is a modification, and in some respects,"

an improvement" upon the structure .of that patent.

., The main objects of this invention are:v

First,' to'provide in a, temporary binder or 'loose sheet holder, an improved structure 4which is capable`A of withstanding heavy strains and ,severe usage without likelihood.

of becoming inoperative, and one in which 'ed out in the claims.

the adjusting mechanismand binding membersmay be repaired should occasion re qnire without materially disturbing the binding. 'Second, to provide an improved temporary binder'br loose sheet holder of 4 Wardly projectingA pivot ears' 1Q. The rodsV by the opening of the book or the swinging` of its covers.

Further objects, andjobjeets relating to structural details willd-efinitely appear from the'detailed description to follow.

I accomplish the objects of my invention byv the devicesand means describedin the following .speciiiqation l The'invention is clearly deiined and point- A structure which vis a preferred embodiment of myinvention is clearlyy illustrated. in the accompanying drawing Yforming a part ofthis specification, in which:

ablebinding 6 of'leather'o'rcanvasisproi' y vided.` The cham'bersin`the'covers gop'en'at the inner ends thereof to reeeivethe back' strip 7 `andthe binding membergsupports,

designated generally `by the'hnmeral 8 in 'Fig- I, consist of th`e"metal barsl 9- and 'the K- reinforcing or backing stripsIO. The barsv -9 are provided .with straplike pivot loops orl knuckles 1l on theirrear sidesfand' rear:

13 of the clamping supports arev pro` vided .with laterallyfturned'- pintles '13 at.

aging these pintle which engage the outer, ends rof'. the covers, 90

the covers being provided' with openings 416 between vthe .inner walls andthe outerTend l pieces to lreceive the `cross pieces 14,- s'e`ev Fig. II.

' The supports are'adapted to be slipped into the cover chambers from the" innerends `of the c overs, .'the` cover frame'-being cut away lat '17-to1receive the rods 13 and theA bindln strips 18,-"see FigIII.,

i n .erablyof leather 'inthe form of flat thongs and extend between the covers and through slots 19 in' the 'clamping member bars 9, the slots .'being y a'lined witlithe pintles' 13' i The adjusting mechanism s trips is l'arranged in' the A'chamber of the for-the binding i cover 2' -and consists of the bar-like'adjust-- l ing. member 20. with which the scre w -2l has threaded engagement, .the member QOAbeing' f l provided'.

with a'nutmember 22 arranged 25 stantially varied by the swinging of the The screw 21 is rotatably `supported suitable .bearing 23 on the cross piece 14S.

The cover is .provided -with a `keyhole-724 the screw -heilig' rotated' by meansvof 'a movable key. 'At their, other ends, .thebindgr y ing strips are securedfto the cross' piece" 1f; of the support in the other cover.

The covers are pivoted upon the binding' I strips, they beingprovided withrigidhinge members 25 connected to` the pivotfears' 12` therein but are supported against substantial springs26.

Vthe other cover by means of studs'27 arlateral swinging movement thereby so that. the binding strips flex at the rear of the bars; 9 and in substantially the plane of A.the piv-,.

ots for the' binding members to the supports and coyers. With the parts' thu s'arranged,

the tension on the binding strips is not s ub-y covers or by the movementof the clampingl bars when the book is opened or closed or otherwise manpulated.- y

The back strip 7 is connected to the eross piece 14 in the cover 1 by means of .the coiled It ,is adjustably connected to ranged through longitudinal slots 28 inthe inner wall of the cover-, #see lFiggVI-the .heads of the studs serving as nger pieces.

. The edges oli' the slots are notched or toothed to receive 'the studs so that the backing is adj ustably connected to the cover. With the back strip thus arranged, the springs 26 yield sui'iciently ier thenormal-adjustment ofthe binder in inserting or removing a few sheets or leaves and when considerable eX- pansion or retraction of the binder is necessary on account 'of theaddition or removal of considerable 'numbers of leaves, the back strip is correspondingly adjusted by means described. f

'lhe .binding mechanism is so supported that/the covers are largely relieved of Strain and great care and skill,is not required in the manufacture and assembling ofpparts.

Further2 the binding member supports may` be made separate :from the cover, lwhich is of substantial advantagein manufacturing.

I have illustrated and describedmy irnprovements in detail in the lform in which I have embodied the same. Whileconsiderable variation in'structural details is' possible, I have not attempted .to illustrate or describe the same herein as I believe the disclosure made will enable those skilled in the art to which this invention relates to adapt the same as conditions or taste may indicate.
